Mobile communication device

Abstract

The invention discloses a mobile communication device which comprises a circuit board and an electric conduction shell, wherein a metallization through hole is arranged in the circuit board, an electric conduction convex pole is arranged on the electric conduction shell and corresponds to the metallization through hole, the electric conduction convex pole is used for fixing the circuit board, and the electric conduction convex pole is in contact with the metallization through hole. By adopting the mode, the mobile communication device is capable of realizing that the metal shell is grounded under the conditions of no individual occupying of a cinnabar space of the circuit board and no individual designing of the metal shell grounding structure.

Description

technical field

[0001] The invention relates to the field of communication equipment, in particular to a mobile communication equipment. Background technique

[0002] At present, metal casings are widely used in various mobile communication devices, and the grounding of metal casings is a key issue considered by designers of mobile communication devices. figure 1 It is a schematic diagram of the distribution of the grounding points of the metal shell of the prior art mobile communication equipment, figure 2 It is a schematic diagram of the distribution of the circuit board grounding points of the prior art mobile communication equipment. Such as figure 1 and figure 2 As shown, in the prior art, a conductive material 11 (for example, conductive cloth or conductive cotton) is pasted on the metal shell 10, and a metal contact area 21 (for example, copper leakage or shielding cover), when the metal shell 10 is fixed to the circuit board 20 , the conductive material 11 is e...
